4x16 The Cohabitation Formulation

Sheldon Cooper: Priya, if you're experiencing any tension or awkwardness, it may stem from the fact that Leonard and Penny used to, if I may quote Howard, "do the dance with no pants."

Priya Koothrappali: So, Penny, Leonard tells me you're an actress. That must be pretty exciting.
Penny: Oh, yeah, yes, real great. Today I drove to Van Nuys for an audition I thought was going to be for a cat-food commercial. It turned out to be porn.
Sheldon Cooper: Did you get the part?
Penny: I didn't do the audition!
Sheldon Cooper: Given the state of your career, can you really afford to be picky?

Priya Koothrappali: Rajesh, Leonard and I have decided to see each other again, and you don't get to tell me who I can or can't have a relationship with.
Sheldon Cooper: Actually, he can. The Hindu code of Manu is very clear in these matters. If a woman's father is not around, the duty of controlling her base desires falls to the closest male member of her family, in this case, Raj. The code also states that if she disobeys, she will be reborn in the womb of a jackal and tormented by diseases. If true, that seems like an awfully large gamble, given that the prize is Leonard.
